Structural and dielectric studies on tungsten bronze oxides (Sr <inf>6</inf>Ti<inf>2</inf>Nb<inf>8</inf>O<inf>30</inf> and Mn doped Sr <inf>6</inf>Ti<inf>2</inf>Nb<inf>8</inf>O<inf>30</inf>)

Tungsten bronze oxides are widely studied due to their various superior physical properties. Sr6Ti2Nb8O30 (STNO) and Mn Doped STNO are synthesized and characterized by X-ray diffraction technique. The structural refinement of STNO is performed using General Structure Analysis System. Dielectric measurements indicate STNO and Mn doped STNO having diffused phase transition. © 2011 American Institute of Physics.
